Abstract: An interface panel structure used in an electric machine; comprises a fixed seat with a fixed seat with a holding element and sliding rails and a movable sliding seat installed therein. Fixing holes for accepting the holding element and sliding grooves operated in cooperation with the sliding rails are disposed in the sliding seat. In addition, a guide rod is installed in the sliding seat for touching off the holding the holding element to separate it from the fixing hole. When the holding element and the fixing hole are engaged, the sliding seat with interface outlets disposed at the front face thereof is hidden in the fixed seat fixed in the electric machine. And, there is no need to open holes on the surface of the electric machine by means of the interface panel structure.

Abstract: An integrated circuit for locating failure process layers. The circuit has a substrate with a scan chain disposed therein, having scan cells connected to form a series chain. Each connection is formed according to a layout constraint of a minimum dimension provided by design rules for an assigned routing layer. Since the connection in the assigned routing layer is constrained to a minimum, the scan chain is vulnerable to variations in processes relevant to the assigned routing layer. The scan chain makes it easier to locate processes causing low yield rate of the scan chain.

Abstract: A circuit for control and observation of a scan chain. The circuit comprises a group of first scan cells connected in series, receiving a first data signal and outputting a second data signal, a multiplexer receiving the first and second data signal, and selectively outputting the first and second data signal in response to a selection signal, and a group of second scan cells connected in series, receiving the first or second data signal from the multiplexer, and outputting a third data signal.

Abstract: A method for in-situ descum/hot bake/dry etch a polyimide photoresist layer and a passivation layer in a singe process chamber is disclosed. A process chamber that can be used for conducting in-situ a descum, a hot bake and a dry etch process sequentially in the same chamber is also disclosed. In the method, a process chamber equipped with a wafer platform and a wafer backside heating and cooling device is first provided, followed by the step of positioning a wafer that has a passivation layer and a patterned polyimide photoresist layer on top of the platform. An oxygen plasma is then generated in the chamber cavity to conduct a descum process, followed by flowing a heated inert gas onto a backside of the wafer to conduct a hot bake process. A cooling inert gas is then flown onto the wafer backside and an etchant gas is flown into the chamber to conduct a dry etch process for forming a via opening in the wafer.

Abstract: A wind-driven perfume dispenser capable of producing different light patterns includes a body portion, a rotatable light-emitting device rotatably mounted on the body portion, and a decoration, the rotatable light-emitting device including an impeller and a light-emitting device mounted on the impeller, whereby the light-emitting device will give light when the impeller is blown by wind and, almost at the same time, the integrated circuit will control the light-emitting diodes to give various kinds of light patterns which will pass through the opening of the decoration to produce a mysterious and appealing appearance, especially at night time.

Abstract: A modal survey flexure fixture of designed to be soft laterally and stiff axially to simulate the same behavior of space shuttle flight latches which support shuttle payloads for payload modal survey verification, qualification and test. The device consists of three major components: an A-Frame which supports flexure rods attached to a trunnion clamp. Flexure rods made of stainless steel with a partially reduced cross section at both ends increase the lateral flexibility for simulating flight conditions. The trunnion clamp is a unique design which takes into account payload integration with the test fixture. The trunnion clamp can be split into upper and lower portions. During the modal survey the lower trunnion clamp acts initially as a place holder for payload installation and alignment. After payload installation and alignment the lower trunnion clamp is combined with the upper trunnion clamp to complete the test fixture configuration.
